德国阿伦（Ahlen）的 Leifeld 是金属旋压装备的标杆品牌，历史可溯至 19 世纪，现为 Schuler 集团成员，产品覆盖灯饰、航空与汽车轮辋行业。其卧式数控旋压机特征：双旋轮对置布局平衡径向力、旋轮座独立液压伺服驱动、主轴扭矩 300–800 N·m，可旋 φ600–2000 mm 件；控制系统内置道次编程器，工程师按"道次-进给-轮位"三元组编程。理解这套装备逻辑，是国产数控旋压机对标与选购二手设备的坐标系。
Leifeld of Ahlen, Germany — tracing back to the 19th century and now part of the Schuler group — is the benchmark in spinning machines for lighting, aerospace and wheel-rim work. Its horizontal CNC spinners pair opposed rollers that balance radial forces with independently servo-hydraulic roller slides and 300–800 N·m spindles, covering φ600–2000 mm. The control ships with a pass programmer built on the pass/feed/roller-position triplet. Understanding this architecture frames both benchmarking domestic machines and buying used equipment.
